IMPROVED EMBROIDERING-ATTACHMBNT FOR SEWING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same. i

To altwhom it may concern a Be it known that I, W. B. BARTRAM, of Danbury, in the county of Fairfield, and State of Connecticut, have invented a ne'wand useful Improvement in Elnbroideririg-Attachment for Sewing-L'Iachines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying,drawings,'in wh'ich- Figure 1 is a perspective view of a sewing-machine, with my improvement attached.

Figure 2 is a front elevation, showing my improvement in operation. v

Figure 3 is an end elevation of the same.

Figures 4 and 5 are side and end elevations of my invention, modified.

Figure 6 is-a 'plan view, showing the operation of my invention, and the work as executed. Y

My invention consists of a swinging braid-carrier, mounted upon the presser-foot, and operated by the needle-arm, and it may be applied to any class'of sewing-machines.

In fig. 1 is represented a perspective view of a sew ing-machine, with my invention in operation.

The various parts of the machine do not require any description, as they are generally understood, and as my attachment maybe readily adapted to any sewing-machine now in use. I will, therefore, confine the description to those parts which form my invention, and its means of attachment to the machine.-

A is the pgesser-foot, the forward end of which may be turned up to form the stud or arm 13, which supports the swin ing braid-carrier C.

The bra'tid-carrierC is pivoted to the arm 13, near its upper end, and the lower end of said' carrier is curved'iorward, and approachesthe needle-hole; and,

at this end, it is pierced with several holes, D, through which strands of cord or braid'may be passed.

There is also a larger hole, E, through the arm B, through which all of said strands are caused to pass before being distributed to the smaller holes D D.

I The upper end of the carrier 0. is expanded late ally, so as to form a long T-heador plate, F, and this plate is provided with a slot, G, runningnearly its whole length, and is provided with notches, H H, in its upper edge.

A wire, I, is attached to the needle-bar, or to the needle-arm, so that itparticipates in all the reciprocatious-ot' the needle, andthe lower end of said wire is looped through the slot G; and, at every upward movement of the needle-arm, said loop engages in one of the notches H H, made in the upper edge. of the slot G, and causes that end of the T- headto be raised up, and the lower end of the carrier-arm G to swing across'in front of the needle-hole.

Supposing, now, the braid-carrier is in the position shown in fig. 3. The needlearm is then at its high-.

est point of elevation.

When the needle descends, the loop at the lower end of the wire I will descend along the slot G, until it has reached nearly or quite to its lower end; then, as the needle begins to rise.

again, said loop will also ascend along said slot until it'engages with the notch H, after which the further upward movement of the needle-arm will produce a movement of the carrier 0, suflicient to reverse its position, asshown in red lines, fig. 3.

By this operation of the T-head F, the lower end of the carrier C, with the holes D D, is transferred from one side of the needle to the other, and, as the ornamental cord iscarried through the holes D D, it will also be transferred from one side. of the needle to the other. At the-next reciprocation, the loop will engage wit-lithe notch H, and the position of the carrier will be again reversed, and so on.

It is easy to perceive, now, that if these movements of the carrier are governed by the needle-arm, and take place withevery reciprocation thereof, when the cloth is fed ibrward, taking the ornamental. cord with it, so that the needle will penetrate alternately upon one and the other side of the braid or cord, and-while the line of stitches may be straight, they will cross at every stitch over the braid or cord, and firmly attach it to the cloth.

Many sewing-machines are now provided with what is'known as the glass foot, and this consists of a suitable'skelet-on-foot, with a glass centre, which may be readily removed, and replaced with the hemming or other attachments.

For the convenieiice of .persons whose sewing-ma.- chines may be provided with said glass foot, I can make my invention with the foot A fasbionedto slide into the seat of the glass foot. y

The wire I may be attached to the needle-carrier or arm, in any convenient way; a. small stud, J, projecting horizontally from said carrier or arm, as shown, being most'convenient.

The details of construction may, of course, be considerably varied, without in any degree changing the nature of the inventiomor its principle of operation.

Having described my invention,

\Vhat I claim as new, is-

1. In combination with the foot A, the swinging braid-carrier O, constructed substantially as described, find for the purpose set forth.

2. In combination with the braid-carrier O, operated by the needle-arm in its reciprocation, and the plate F, provided with the slot G and notches Il'H, the looped wire I, substantially as and for the purpose set forth. T
